2026 Top 10 Oil Sealed Vacuum Pump Suppliers in China

Introduction to Oil Sealed Vacuum Pump

An oil - sealed vacuum pump is a type of positive - displacement pump that uses oil as a sealing and lubricating medium. It operates by creating a vacuum through the movement of mechanical components within a chamber filled with oil. The oil serves multiple crucial functions. Firstly, it seals the clearances between the moving parts, preventing the backflow of gas and improving the pump's efficiency in achieving and maintaining a low - pressure environment. Secondly, it lubricates the mechanical parts, reducing friction and wear, which extends the service life of the pump. Thirdly, the oil helps to cool the pump by absorbing the heat generated during the compression process.

Oil - sealed vacuum pumps are widely used in various industries. In the semiconductor industry, they are essential for creating the high - vacuum conditions required for processes such as thin - film deposition and etching. In the food packaging industry, these pumps are used to remove air from packages to extend the shelf - life of products. They are also used in laboratories for vacuum distillation, freeze - drying, and other experiments that demand a controlled vacuum environment.

Now, let's take a look at the top 10 oil - sealed vacuum pump suppliers in China in 2026.
